PLOW.

Application filed February 20, 1928. Serial No. 255,766.

This invention relates to plows particularly useful in connection with irrigated lands, and contemplates a novel construction of means for adjusting the plow shares and colters to regulate the depth of'the furrow, in addition to a novel construction of means for elevating the plow beams and supporting the latter spaced above the ground.

The nature and advantages of the invention will be better understood from the following detail description taken in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this application like numerals of reference indicate similar parts in the several views and wherein Figure 1 is a plan view.

Figure 2 is a side elevation with one of the ground wheels removed.

Figure 3 is a sectional View on line 33 of Figure 1 Figure 4: is a sectional view on line 44 of Figure 1.

Figure 5 is a sectional view on line 55 of Figure 1.

Referring to the drawings in detail 10 indi cates a cross beam to which the tongue 11 is secured. Attached to the opposite sides of the tongue are angular shaped rods 12 which extend in divergent relation from the tongue and are secured to the cross beam 10 by suitable brackets 13. The rods include spaced parallel portions which are offset to provide axles for the ground wheels 14, these rods together with the cross beam 10 constitutes the frame of the plow. The operators seat is indicated at 15 and is suitably supported from the tongue 11.

Journaled in suitable bearings 16 secured to the cross beam 10 is a transverse rod 17, and at opposite sides of the tongue, this rod is formed with substantially yoke shaped portions 18. A pair of spaced beams 19 are journaled on each of the yoke shaped portions 18 and support a colter 20, the latter being arranged directly in advance of the plow share 21 carried by a suitable beam 22 arranged between beams 19 above referred to. Each beam 22 is pivoted upon a transverse rod 23 arranged parallel with the rod 17, while arranged beneath the adjacent beams 19 is a plate 241 from which rises suitable hooks 25 reposing upon the rod 23. A

similar rod26 is arranged below the plow beams 22 and held associated therewith by hooks 27 rising from a plate 28 arranged beneath the plow beams 19. A similar'rod 29 is arranged above the plow beams 22 at a point rearwardly of the plow beams 19 and held associated with said beams 22 by hooks 30 rising from a plate 31 securedbeneath each beam 22. These rods afiord the structure maximum strength and rigidity, While the rod 26 is also utilized in lifting the plow beams 22 in the manner to be hereinafter described.

For the purpose of lowering the colters 20 and plow shares 21 to regulate the depth of the furrow, I employ a lever 32 which is secured to the rod 17 arranged adjacent the cross beam 10, and manifestly by operating this lever 22, the yoke shaped portions 18 of said rod may be positioned horizontally or I vertically as illustrated in Figuresl and 4. The lever 32 is provided with a pawl 33 which cooperates with a rackbar 341 to hold the lever and the respective plow beams in a given position.

Rising from the spaced parallel portions of the rods 12 are brackets 35 which support a cross member 36, the latter being suitably braced by diagonally arranged elements 37 secured to the cross beam 10 as illustrated in Figures 1, 2 and 3. Rising from the cross member 36 are apertured lugs 38 constituting bearings for a shaft 39, the latter being rocked through the instrumentality of a lever 40. The lever is provided with a pawl 41 which cooperates with a rack bar 42 for holding the lever fixed in a given position. Crank arms 43 project from the shaft 39 and are connected with the rod 23 by links 44, so that when the lever 40 is moved in one direction, the rod 23 is lifted as illustrated in Figure 3, thereby lifting the plow beams 22, and also lifting the plow beams 19 which are supported on the rod by the hooks 25. However, the plow beams 22 are pivoted on this rod, and when the beams are lifted as illustrated in Figure 3, the plow beams 22are engaged and supported by the rod 26 as illustrated. Consequently the lever 32 is utilized to regulate the draft of the plow and the depth of the furrow, while the lever 40 is utilized for lifting the plows above the ground when so desired. Both levers are arranged adjacent the operators seat 15.

l/Vhile it is believed that from the foregoing description the nature and advantages of the llO invention will be readily apparent, I desire to have it understood that I do not limit myself to the exact construction and arrangement of parts herein sl1own,and that such changes may be resorted to when desired as fall within the scope of what is claimed.

What is claimed is:

lqIn a plow, a wheeled frame, a trans verse rod journaled on the frame, spaced'pairs of plow beams pivoted on said rod, a colter supported by each pair of beams, a transverse rod arranged in spaced parallel relation to the first mentioned rod and supported upon said plow beams, an additional plow beam arranged between each pair of said beams and pivoted on the last mentioned rod, a plow share carried by each of the last mentioned beams, and means for rocking the first mentioned rod to regulate the draft of the plow and the depth of the furrow as described.

2. In a plow, a wheeled frame including a front beam, a transverse rod journaled on I saidbeam and including spaced yoke like porand means for rocking the first mentioned rod to vary the position of said yoke like v portions, and thereby regulate the draft of the plow and the furrow being cut.

8. In a plow, a wheeled frame including a beam, a transverse rod journaled on said beam and including spaced yoke like portions,

a pair of spaced plow beams journaled on each yoke like portion and supporting a colter, a second transverse rod arranged at the rear of thefirst mentioned rod and reposing upon said plow beams, means for holding said rod associated with said beams, an additional plow beam positioned between each pair of said beams and pivoted on the last mentioned rod, a plow share carried by each of the last mentioned beams directly behind the adjacent colters, means for rocking the first mentioned rod to vary the position of said yoke like portions and thereby regulate the draft of the plow and the depth of the furrow being cut, a shaft journaled upon the frame, arms projecting from the shaft, links connecting the arms with the second mentioned rod, and means for rocking said shaft to lift said beams above the ground, and a transverse rod supported by the first mentioned beams and adapted to engage and support the second mentioned beams when all of said beams are elevated. v

In testimony whereof I affix my signature.
